TD23 Cylinder Head for Nissan D22 Pickup — OEM 11039-3S900

This complete cylinder head assembly is manufactured to OEM specifications for the Nissan TD23 2.3-liter diesel engine, the original equipment powerplant in the Nissan D22 Navara / Frontier pickup and various Nissan forklift models. The cylinder head is the most complex and thermally stressed casting on any engine — it seals the combustion chambers, houses the valves and valve train, contains the intake and exhaust ports, integrates the injector mounting bores, and provides the coolant and oil passages that regulate operating temperature. A cracked, warped, or valve-damaged cylinder head manifests as white smoke from coolant burning, oil in the coolant, compression loss between cylinders, or persistent overheating — symptoms that cannot be resolved with a gasket change alone and require complete head replacement.

This cylinder head is cast from high-grade alloy gray iron using precision sand-casting techniques that ensure uniform wall thickness and port geometry matching the original Nissan TD23 design. After casting, the head undergoes full CNC machining of the deck face, valve seats, injector bores, glow plug threads, and camshaft bearing journals to exact OE tolerances. The deck surface is ground to a flatness specification of less than 0.03mm across the full length, ensuring a perfect seal with the head gasket without the need for additional machining. Valve seats are precision-cut with multi-angle profiles for optimal airflow and heat transfer, and the pre-installed valve guides are reamed to factory clearance specifications. Each head is pressure-tested for coolant and oil passage integrity before leaving the factory.

Direct replacement for Nissan TD23 engines in D22 Navara/Frontier pickups (1997-2004), Nissan TD23-powered forklifts, and Nissan Urvan / Caravan commercial vehicles. Also fits industrial equipment and generator sets utilizing the TD23 platform. Always replace the head gasket, head bolts (TD23 uses torque-to-yield bolts), and intake/exhaust manifold gaskets when installing a new cylinder head. Follow the factory torque sequence precisely.
